How much lift for these flow numbers

Post by tcb3274 »

Here are the flow numbers for a set of Trick Flow 195 heads that have been ported by Eric Weingartner. How much lift should I be looking for in a camshaft?

.200 -141
.300 - 194
.350 - 216
.400 - 237
.450 - 255
.500 - 269
.550 - 280
.600 - 285
.650 - 288
.700 - 290

Thanks

I'd go for around .600 on the intake and .550 on the exhaust. Duration around 240-250 @ .050. I like cams on the conservative side.

Did Eric port these heads for you??
If so probably best to ask for his recommendation on a cam for your combination,
If not then you would be best to give all the details of engine, trans, converter, rear gear etc etc
Can't pick a cam by flow numbers alone

These flow numbers look like the first step to a potent build.
Give me the head port volume and the engines CID, CR RR, rod length, peak power rpm required, Vacuum required what type of cam you want (flat -solid -hyd -roller) And I will run some numbers for you cam wise that will make the most of what will probably be a set of great heads. Also give you the power and torque output to within +/- 3%.

The 240 to 250 @ .050 duration was more on the hot side. For a street cruiser I'd try and get the same lift numbers but with 220 to 230 duration @ .050. Maybe even less if you want more street manners. Most people error on the side of too big of a cam. You can make good power with a small cam and a nice set of heads.

I would first want to know what a pleasing hp goal would be for you and how many street miles are we talking per year?

Steve, yes he did port them for me.

I will place a call into him.

Thank you Mr Vizard for reply. Your reputation speaks for itself.

Im not sure I understand what head port volume is.

The engine is a 383, 10 to 1, 5.7 rod, peak power somewhere in the 6000 to 6500 rpm band, no requirements on vacuum, hyd. roller. We shot for anywhere between 450 horsepower and 500 horsepower.

I feel those numbers are about right too. Looking to make great power with a lesser cam.

I had a 67 Camaro with a similar setup. My favorite upgrade was going to a TKO-500 5 speed with an overdrive fifth gear. Made 70 mph at around 2500 rpm's.

I would guess the intake port CC, for example 180, 195, 215 etc
